SEQUOIA REDWOOD

Steve Boyd & James R. Griffin


1 sp.: western North America. (Sequoyah, Cherokee chief, 1776?–1843)
Unabridged etymology: (John Lockhart has indicated (7 Jul 2004 Interchange Feedback) that, according to Asa Gray, no one has ever found, in the writings of Endlicher (author of the genus name Sequoia), any mention of Sequoyah, the Cherokee chief for whom the genus Sequoia is often said to have been named (in Cherokee, "sequoyah" means "opossum"), and that Gray instead believed that the stem of the word was a derivation from the Latin "sequi" or "sequor," meaning "sequence" or "following," in reference to the fact that redwoods were remnants or followers of numerous fossil ancestors.)

S. sempervirens (D. Don) Endl.
NATIVE
Tree, plant generally sprouting vigorously from base if cut, from entire crown if burned. Stem: trunk < 110 m, to 9 m diam; old crown narrowly conic to ± cylindric, generally unbranched in lower 1/2; bark < 30 cm thick near base, fibrous, ridged, red-brown; branches downswept to ± ascending; twigs persistent < 4 years. Leaf: alternate, green < 3 years, persistent < 4; of 2 kinds, those on sprouting, rapidly growing, or fertile stems appressed, not ranked, < 8 mm, awl-like, others spreading, ± 2-ranked, 5–25 mm, linear (to lance-linear), generally flat. Pollen cone: 2–5 mm, ± spheric to ovoid. Seed cone: 13–35 mm, ± spheric, woody, maturing in 1 year, persistent < 2; scales peltate, fused to bracts. Seed: 2–7 per scale, 3–6 mm, wings 2, narrow, lateral.
n=33. Redwood forest; < 1100 m. w Klamath Ranges, Outer North Coast Ranges, w Inner North Coast Ranges, n&c Central Coast, San Francisco Bay Area, n Outer South Coast Ranges; southwestern Oregon. Tallest trees in North America. [Online Interchange]
